       Hello,

         

      after reading of

      I tried to get it to run on my CY8CKIT- 014 with a PSoC5 ES1.

         

      Result:  38208 Byte Flash,   8508  SRAM, (after combing the huge CMSIS library)

         

      Measured time was:  23,5 ms per FFT   (1024 points, 32Bit float format,  60Mc processor clock)

         

      The full CMSIS- sample reached 56 ms  with

         
      - calculating the magnitude at each bin
      - Calculating of maxValue and returning corresponding BIN value  I am happy, that the PSoC5 satisfies my goals.
